POWER WHEEL.

plantation med August 27, 1921.

To all whom it may concern:

Be it known that ll, HERBERT L. THOMP- soN, a citizen of the United States, and a resident of the city of Elgin, in the county of Kane and State of Illinois., have invented certain new and useful Improvements in Power Wheels, of which the following is a specification.

My invention relates to a rotary water motor of the impact type and its object is to provide a simple, inexpensive device of this class which can be operated by a stream or jet of small volume but relatively high velocity to develop a considerable amount of power. The small amount of water used per unit of time makes it possible to enclose the rotary water wheel in a small, compact housing. The wheel itself may be made quite small relative to the power which it develops so that the friction at its bearings is reduced to a minimum.

The motor is shown in the drawing as used for operating a culinary beater but is not claimed herein in that connection,- the motor in combination with the beater being claimed in a co-pending application filed as a divi-sion hereof November 19, 1921, as Serial No.' 516,275. This application is concerned solely with the motor as such which might be put to various diii'erent useful purposes.

1n the drawing Fig. 1 is a vertical sectional view of the motor shown as forming a part of the beating apparatus of my co-pending application above referred to.

Fig. 2 is a plan view of the device with the motor wheel housing broken away to show the wheel,;and

Fig. 3 is a view, in perspective, of the wheel.

Referring to the drawing, the wheel 24 is shown as secured to the upper end of a shaft 15, which shaft has an upper bean ing 21, 22 and a lower bearing 16 in stationary beating member 4. rll`he shaft is shown as provided With a rotary beating element 18, 19. 20 and projects into a jar 9 secured to a cap 6 which is riveted at 13 to the under side of the water Wheel casing 26, 26, the parts lof which are beaded together at 27.- 28 is a thimble extending into the top of the casing and provided with a union for attaching the casing to the down turned end of a water faucet, for example. Thimble 28 is formed with a relatively Serial No. 496,090.

small jet orifice 29 for drecting a jet of water across the wheel 24 in a plane substantially parallel to the plane of the wheel. 33 is a water discharge pipe leading from the casing and 37 a small opening in the top of the casing to prevent the formation of a vacuum in the casing.

The water wheel consists preferably of a sheet metal disc 24 which is slit along preferably substantially straight lines oblique at acute angles to radii of the disc from the periphery of the disc inwardly to points spaced from its center, with the portions of the disc between the periphery and the slits bent up to provide vanes A, B, C, D,

E and F. These vanes are preferably curved p transversely with respect to their length so as to provide lwater receiving surfaces which are concave, that is,approximately semitubular.

In operation the Water jet from aperture 29, which is of small diameter but of considerable velocity, impinges against the concave faces of the vanes so as to impart rotary movement to the wheel, the jet being centered on the vanes because of their transversely vconcave contour. The stream of water impinging on each of the vanes is directed thereby across the open center of the wheel to the vane next but one beyond the vane of first impingement, the deflected jet impinging upon the concave surface of such other vane so as to give an additional forward rotary impulse to the wheel. That is, the water flowing from. vane A passes across` the wheel and impinges upon vane C. When the vane F is played upon by the jet the stream deflected therefrom impinges against B and so on. The transversely concave contour of the vanes keeps the water jet impinging on the vanes from spreading and dissipating its force. Because ofthe small volume of water employed per unit of vtime the housing of the water wheel may be made small and compact.
